The History of Mobile Phone

In 1983, the world’s first mobile phone came out. It was Motorola DynaTAC. You would never have imagined the weight of this mobile phone. It weighed two pounds, equivalent to about 900 grams, and sold for 3,995 dollars. You know, at that time, that was a huge sum of money. The research of this mobile phone exceeded 10 years. Since then, the “weight loss” of the mobile phone has become faster and faster. Miniaturization and lightness were the goals of the mobile phone at that time.

By 1831, Faraday of France discovered the magical phenomenon of electromagnetic induction. Maxwell expounded the research results of Faraday and others with mathematical formulas. They popularized the theory of electromagnetic induction to the world.

142 years later, a man stood on the street and took out a wireless phone. The size of it was about the same as two bricks. After dialing the number, he started the call. This man was Martin Cooper, the inventor of the mobile phone. At that time, he was a Motorola employee.

In the 1980s, the mobile phone that appeared in American movies and TV works was first developed by Dr. Cooper of Motorola Company. This is the first generation (1G) mobile phone. The second generation is the most common mobile phones. These mobile phones have stable call quality and appropriate standby time.

By the 21st century, the mobile phone industry has exploded. The flip covers, slide covers and touch screens emerging one after another. Nokia, Lenovo, Xiaomi, until the iPhone appeared, knocked on the door of smart phones. Almost all the well-known companies have begun to attack the mobile phone screen. The era of full screen has followed. For example, Xiaomi MIX’s three-sided equal width full screen. HUAWEI HONOR 10 Lite‘s water drop full screen, iPhone x’s special-shaped full screen, etc. No one can imagine mobile phones can get this far.

After so many changes in mobile phones, the improvement is not only the screen, but also the processor. The network speed and endurance have been a great improvement. A strong processor is the core of the mobile phone. With the blessing of the processor, we can do more and more things with the mobile phone. In terms of network speed, the arrival of 5G era will be more glorious than 4G. If we are in the 3G era, we will feel that the increase in network speed at 4G will not be of great use. So is 5G. But is it true that the only increase in 4G is network speed? With the blessing of faster Internet speed, many industries have spawned. The rise of the short video industry and the arrival of the Internet are beyond expectation. The disturbance caused by 5G’s faster and faster network speed is not worse than 4G.

The battery life of the mobile phone is one of the keys. In the past, the mobile phone could last for 30 minutes. But today, you may only need to charge for 5 minutes to talk for half an hour.

The mobile phone industry always refreshing our eyes. What will the mobile phone look like in the future? Let’s wait and see.
